Description
本發明係有關於一種馬達結構,特別是一種混合式馬達結構。 The present invention relates to a motor structure, and more particularly to a hybrid motor structure.
一般而言,具雙轉子之馬達則需要具備對應的雙定子,各個定子上需要設置線圈以驅動對應的轉子,然而,上述的設計會使馬達的體積、重量及成本大幅增加,且由於設計上的缺失,上述的設計也無法在滿足低速高扭力的情況下同時兼顧寬廣轉速域的需求。 In general, a motor with dual rotors needs to have a corresponding double stator, and each stator needs to be provided with a coil to drive the corresponding rotor. However, the above design will greatly increase the size, weight and cost of the motor, and due to the design. The lack of the above design can not meet the needs of a wide range of speeds while meeting low speed and high torque.
而由於電動車之輪內驅動馬達或一體式啟動發電機(Integrated Starter Generator,ISG)等等許多應用上有體積及重量的限制,又需要滿足低速高扭力及並能同時兼顧寬廣轉速域,因此上述的設計已無法達到實際上的應用需求。 However, due to the size and weight limitations of many applications such as electric wheel drive motors or Integrated Starter Generators (ISGs), it is necessary to meet low speed and high torque and to simultaneously accommodate a wide range of speeds. The above design has not been able to meet the actual application needs.
美國專利第US20130093276號揭露一種具有雙轉子的馬達,其利用定子內的不導磁層防止多組線圈之間的相互干擾,然而,此前案雖然可以防止多組線圈之間的相互干擾,但其定子內需要設置不導磁層,因此也會使馬達的體積、重量及成本增加。 U.S. Patent No. US20130093276 discloses a motor having a dual rotor that utilizes a non-magnetically permeable layer in the stator to prevent mutual interference between a plurality of sets of coils. However, although the prior case can prevent mutual interference between multiple sets of coils, It is necessary to provide a non-magnetic conductive layer in the stator, which also increases the size, weight and cost of the motor.
美國專利第US7030528號揭露一種具有雙轉子的馬達,其具備內定子、外定子、內轉子及外轉子的特殊結構,以防止設置於內定子之線圈與設置於外定子之線圈之間的相互干擾,然而,此前案雖然可以防止多組線圈之間的相互干擾,但由於其仍具備雙定子結構,故無法有效地降低馬達 的體積、重量及成本。 US Pat. No. 7,030,528 discloses a motor having a dual rotor having a special structure of an inner stator, an outer stator, an inner rotor and an outer rotor to prevent mutual interference between a coil disposed on the inner stator and a coil disposed on the outer stator. However, although the previous case can prevent mutual interference between multiple sets of coils, it cannot effectively reduce the motor because it still has a double stator structure. Volume, weight and cost.
美國專利第US6924574號揭露一種具有雙轉子的馬達,其具備雙轉子及單定子的特殊結構,其雖然可以降低馬達的體積、重量及成本,但設置於單定子上的多組線圈仍會相互干擾,且定子線圈配置方式限制較多,故使用上缺乏彈性。 U.S. Patent No. 6,924,574 discloses a motor having a dual rotor having a special structure of a double rotor and a single stator, which can reduce the size, weight and cost of the motor, but the multiple sets of coils disposed on the single stator still interfere with each other. And the stator coil configuration is more limited, so there is a lack of flexibility in use.
因此,如何提出一種馬達,能夠有效改善習知技藝之馬達體積過大、重量過高、成本過高、使用上缺乏彈性及無法在體積及重量限制的情況下達到低速高扭力及寬廣轉速域的情況已成為一個刻不容緩的問題。 Therefore, how to propose a motor can effectively improve the motor of the prior art, which is oversized, overweight, overcosted, inflexible in use, and unable to achieve low speed, high torque and wide speed range under the limitation of volume and weight. It has become an urgent issue.

The prior art of the present invention, which is used in the prior art, is only referred to herein by reference.
請參閱第1圖,其係為本發明之混合式雙轉子馬達結構之第一實施例之第一示意圖。如圖所示,混合式雙轉子馬達結構1可包含定子11、第一轉子12A、第二轉子12B、第一線圈13A、第二線圈13B及第一磁鐵組14A第二磁鐵組14B。 Please refer to FIG. 1 , which is a first schematic view of a first embodiment of a hybrid dual rotor motor structure of the present invention. As shown, the hybrid dual rotor motor structure 1 can include a stator 11, a first rotor 12A, a second rotor 12B, a first coil 13A, a second coil 13B, and a first magnet group 14A second magnet group 14B.
定子11可包含複數個定子齒111;第一轉子12A可與定子11成徑向設置,第一磁鐵組14A可設置於第一轉子12A之內表面之周圍;第二轉子12B可與定子11成徑向設置,第二磁鐵組14B可設置於第二轉子12B之內表面 之周圍,在本實施例中,由徑向方向觀之,定子11可設置於第一轉子12A及第二轉子12B之內;在本實施例中,第一轉子12A與第二轉子12B可均為永磁式轉子;在其它較佳的實施例中,第一轉子12A與第二轉子12B中之一可為永磁式轉子,而另一個可為感應式轉子。 The stator 11 may include a plurality of stator teeth 111; the first rotor 12A may be radially disposed with the stator 11, the first magnet group 14A may be disposed around the inner surface of the first rotor 12A; and the second rotor 12B may be formed with the stator 11. Radially disposed, the second magnet group 14B may be disposed on the inner surface of the second rotor 12B In the present embodiment, the stator 11 can be disposed in the first rotor 12A and the second rotor 12B in the radial direction; in the embodiment, the first rotor 12A and the second rotor 12B can both be disposed. It is a permanent magnet rotor; in other preferred embodiments, one of the first rotor 12A and the second rotor 12B may be a permanent magnet rotor and the other may be an inductive rotor.
第一線圈13A可繞設於該些定子齒111上。第二線圈13B可繞設於該些定子齒111上。其中,第二線圈13B可包含複數個子線圈組,該些子線圈組可為串聯或並聯,各個子線圈組包含複數個子線圈,該些子線圈可為串聯或並聯,而第二線圈13B之極對數可為第一線圈13A之極對數之一整數倍。第一線圈13A與第二線圈13B可以為各式各樣不同的形式,如環形(Toroidal)線圈等等。 The first coil 13A can be wound around the stator teeth 111. The second coil 13B can be wound around the stator teeth 111. The second coil 13B may include a plurality of sub-coil groups, which may be connected in series or in parallel. Each sub-coil group includes a plurality of sub-coils, which may be connected in series or in parallel, and the second coil 13B The logarithm may be an integer multiple of one of the pole pairs of the first coil 13A. The first coil 13A and the second coil 13B may be in various different forms, such as a Toroidal coil or the like.
此外,第一線圈13A可包含變極結構,變極結構可包含複數個切換元件,並可藉由切換該些切換元件以改變第一線圈13A之極數;同樣的,第二線圈13B可包含變極結構,變極結構可包含複數個切換元件,並可藉由切換該些切換元件以改變第二線圈13B之極數。因此,混合式雙轉子馬達結構1可藉由整合此特殊的變極結構以提供更多不同的動力特性,而上述之變極結構之詳細技術內容已於中華民國專利申請號第101129353號揭露,故不在此多加贅述。 In addition, the first coil 13A may include a pole-changing structure, the pole-changing structure may include a plurality of switching elements, and the number of poles of the first coil 13A may be changed by switching the switching elements; likewise, the second coil 13B may include In the pole-changing structure, the pole-changing structure may include a plurality of switching elements, and the number of poles of the second coil 13B may be changed by switching the switching elements. Therefore, the hybrid dual-rotor motor structure 1 can provide more different dynamic characteristics by integrating the special variable pole structure, and the detailed technical content of the above-described variable pole structure is disclosed in the Republic of China Patent Application No. 101129353. Therefore, I will not repeat them here.
請參閱第2圖及3圖,其係為本發明之混合式雙轉子馬達結構之第一實施例之第二示意圖及第三示意圖。第2圖及第3圖例示了本實施例的三相線圈之繞線之示意圖。 Please refer to FIG. 2 and FIG. 3, which are a second schematic diagram and a third schematic diagram of the first embodiment of the hybrid dual-rotor motor structure of the present invention. 2 and 3 illustrate schematic views of the winding of the three-phase coil of the present embodiment.
由於本發明所提出的電機架構之定子具有多個線圈,因此,如此透過合適的磁極關係,使多個線圈之間的磁通鏈結能夠降到最低也成為了一個重要課題,如此則可以維持馬達驅動時良好的獨立性以分別獨立地驅動第一轉子12A及第二轉子12B,進而達到精準的馬達控制。 Since the stator of the motor structure proposed by the present invention has a plurality of coils, it is an important subject to minimize the flux linkage between the plurality of coils through a suitable magnetic pole relationship, so that it can be maintained. The motor is driven with good independence to independently drive the first rotor 12A and the second rotor 12B, respectively, to achieve precise motor control.
如第2圖分別例示了本實施例第一線圈13A之U相、V相及W相的繞線方式,其極對數S1為1。如第3圖分別例示了本實施例第二線圈13B之U相、V相及W相的繞線方式,其極對數S2為4,故第二線圈13B之極對數S2為第一線圈13A之極對數S1的4倍。 The winding mode of the U phase, the V phase, and the W phase of the first coil 13A of the present embodiment is exemplified in Fig. 2, and the number of pole pairs S1 is 1. As shown in FIG. 3, the U-phase, V-phase, and W-phase winding modes of the second coil 13B of the present embodiment are respectively illustrated, and the pole pair number S2 is 4, so that the pole pair number S2 of the second coil 13B is the first coil 13A. The pole number is 4 times that of S1.
也就是說,在第一線圈13A的極對數S1等於1時,第二線圈13B之極對數S2需要為第一線圈13A的極對數S1之大於1的整數倍,即:第一線圈之極對數S1=1;第二線圈之極對數S2=n(n>1);在本實施例中,第一線圈13A的極對數S1與第一磁鐵組14A的極對數的總和可等於定子11之定子齒111的數量,且第二線圈13B的極對數S1等於第二磁鐵組14B的極對數,如此也可有效地減少第一線圈13A及第二線圈13B之間的磁通鏈結。 That is, when the pole pair number S1 of the first coil 13A is equal to 1, the pole pair number S2 of the second coil 13B needs to be an integer multiple of the pole pair number S1 of the first coil 13A greater than 1, that is, the pole pair of the first coil S1=1; the pole pair of the second coil S2=n(n>1); in this embodiment, the sum of the pole pairs S1 of the first coil 13A and the pole pairs of the first magnet group 14A may be equal to the stator of the stator 11 The number of teeth 111, and the number of pole pairs S1 of the second coil 13B is equal to the number of pole pairs of the second magnet group 14B, so that the flux linkage between the first coil 13A and the second coil 13B can be effectively reduced.
而在其它較佳的實施例中,第一線圈13A的極對數S1可大於1,同樣的,第二線圈13B之極對數S2需要為第一線圈13A的極對數S1之大於1的整數倍,即:第一線圈之極對數S1=q(q>1);第二線圈之極對數S2=nq(n>1);當然,上述僅為舉例,在其它較佳的實際例中,第一線圈13A的極對數S1及第二線圈13B的極對數S2還可以有多種不同的配置,本發明並不以此為限。 In other preferred embodiments, the pole pair number S1 of the first coil 13A may be greater than 1. Similarly, the pole pair number S2 of the second coil 13B needs to be an integer multiple of the pole pair number S1 of the first coil 13A greater than 1. That is, the pole pair S1=q (q>1) of the first coil; the pole pair S2=nq (n>1) of the second coil; of course, the above is only an example, in other preferred practical examples, the first The pole pair number S1 of the coil 13A and the pole pair number S2 of the second coil 13B can also have various configurations, and the invention is not limited thereto.
由上述可知,為了能夠有效地降低第一線圈13A及第二線圈13B之間的磁通鏈結,本實施例提及了上述幾種較佳的線圈設置。其中,在本實施例中,第二線圈13B之極對數可為第一線圈13A之極對數之一整數倍,第一線圈13A的極對數可大於或等於一對。除此之外,第二線圈13B之子線 圈組的數量可為該整數倍之大於一的因數。例如,若第一線圈13A的極對數為S1,而第二線圈13B的極對數為S2,則第二線圈13B之子線圈組的數量則為S2/S1之大於一的因數;若S2/S1=6,則第二線圈13B之子線圈組的數量則可以為2、3或6。 As apparent from the above, in order to effectively reduce the flux linkage between the first coil 13A and the second coil 13B, the present embodiment has mentioned several preferred coil arrangements as described above. In this embodiment, the pole pair of the second coil 13B may be an integer multiple of one of the pole pairs of the first coil 13A, and the number of pole pairs of the first coil 13A may be greater than or equal to a pair. In addition to this, the sub-line of the second coil 13B The number of circle groups may be a factor greater than one of the integer multiples. For example, if the number of pole pairs of the first coil 13A is S1 and the number of pole pairs of the second coil 13B is S2, the number of sub-coil groups of the second coil 13B is a factor greater than one of S2/S1; if S2/S1= 6, the number of sub-coil groups of the second coil 13B may be 2, 3 or 6.
透過上述的設置,可使本發明之混合式雙轉子馬達結構之第一線圈13A及第二線圈13B之間的磁通鏈結降低,如此則可以維持馬達驅動時良好的獨立性,使操控時能夠同時對第一轉子12A及第二轉子12B進行獨立控制,進而達到精準的馬達控制,以提供更佳的效能。 Through the above arrangement, the flux linkage between the first coil 13A and the second coil 13B of the hybrid dual-rotor motor structure of the present invention can be reduced, so that the motor can be maintained with good independence during driving, so that the control can be performed. The first rotor 12A and the second rotor 12B can be independently controlled at the same time, thereby achieving precise motor control to provide better performance.
此外,由於第一線圈13A及第二線圈13B之間的磁通鏈結已有效地降低,定子11也不需要設置不導磁層,使混合式雙轉子馬達結構1之體積、重量及成本大幅降低。當然,上述的設置僅為舉例,線圈的繞線可依實際應用的需求而改變,本發明並不以此為限。 In addition, since the flux linkage between the first coil 13A and the second coil 13B has been effectively reduced, the stator 11 does not need to be provided with a non-magnetic conductive layer, so that the volume, weight and cost of the hybrid dual-rotor motor structure 1 are large. reduce. Of course, the foregoing setting is only an example, and the winding of the coil may be changed according to the requirements of the actual application, and the invention is not limited thereto.

如同上述,為了維持馬達驅動時良好的獨立性,進而達到精準的馬達控制,使操控時能夠同時對第一轉子12A及第二轉子12B進行獨立控制,使多個線圈之間的磁通鏈結降到最低變的極為重要,而本實施例透過子線圈的特殊串聯並聯關係可進一步降低多個線圈之間的磁通鏈結,本實施例中舉例說明了數種較佳的方式。 As described above, in order to maintain good independence when driving the motor, and thus achieve precise motor control, the first rotor 12A and the second rotor 12B can be independently controlled at the same time to control the flux linkage between the plurality of coils. It is extremely important to minimize the variation, and in this embodiment, the flux linkage between the plurality of coils can be further reduced by the special series-parallel relationship of the sub-coils, and several preferred modes are exemplified in this embodiment.

如圖所示,第二線圈13B包含4個子線圈S1-S4,子線圈S1與對應的子線圈S3並聯形成一個子線圈組SG1,子線圈S2與對應的子線圈S4並聯形成一個子線圈組SG2,子線圈組SG1與子線圈組SG2並聯,圖中箭頭AR1所示之定子圓周方向為電氣角0~360度。 As shown, the second coil 13B includes four sub-coils S1-S4, the sub-coil S1 is connected in parallel with the corresponding sub-coil S3 to form one sub-coil group SG1, and the sub-coil S2 is connected in parallel with the corresponding sub-coil S4 to form one sub-coil group SG2. The sub coil group SG1 is connected in parallel with the sub coil group SG2, and the circumferential direction of the stator indicated by the arrow AR1 in the figure is an electrical angle of 0 to 360 degrees.
由上述可知,較佳的,當各個子線圈組SG1、SG2之子線圈之數量為偶數,且沿定子11之圓周之機械角之0~360度上或第一線圈13A之磁場之電氣角之0~360度上平均分佈時,各個子線圈組SG1、SG2之該些子線圈可為並聯,而該些子線圈組SG1、SG2之間可為並聯。當然,在另一較佳的實施例中,該些子線圈組SG1、SG2之間可為串聯。而在其它較佳的實施例中,各個子線圈組SG1、SG2之該些子線圈也可為串聯,而該些子線圈組SG1、SG2之間則可為串聯或並聯。 It can be seen from the above that, when the number of sub-coils of each sub-coil group SG1, SG2 is an even number, and the electrical angle of the magnetic field of the first coil 13A is 0 to 360 degrees along the circumference of the stator 11 or 0. When the average distribution is ~360 degrees, the sub-coils of the respective sub-coil groups SG1, SG2 may be connected in parallel, and the sub-coil groups SG1, SG2 may be connected in parallel. Of course, in another preferred embodiment, the sub-coil sets SG1, SG2 may be connected in series. In other preferred embodiments, the sub-coils of the sub-coil groups SG1 and SG2 may also be connected in series, and the sub-coil groups SG1 and SG2 may be connected in series or in parallel.
當然,其它較佳的實施例中,各個子線圈組SG1、SG2之該些子線圈可為串聯,子線圈組SG1與子線圈組SG2則可以是以串聯或並聯的方式連結。 Of course, in other preferred embodiments, the sub-coils of each of the sub-coil groups SG1 and SG2 may be connected in series, and the sub-coil group SG1 and the sub-coil group SG2 may be connected in series or in parallel.
如第5圖所示,第一線圈13A的極對數為1,第二線圈13B之極對數為6,第二線圈13B可為三相線圈,即U相、V相及W相,這裡以第二線圈13B之U相為例,其可包含複數個子線圈S1-S6,該些子線圈S1-S6可繞設於定子11上,使第二線圈14可包含複數個子線圈組SG1-SG2,且各個子線圈組之子線圈數量為3(奇數),該些子線圈組SG1-SG2之間可為並聯,第二線圈14的極對數可為各個子線圈組SG1-SG2之子線圈數量的整數倍。 As shown in FIG. 5, the number of pole pairs of the first coil 13A is 1, the number of pole pairs of the second coil 13B is 6, and the second coil 13B can be a three-phase coil, that is, a U phase, a V phase, and a W phase. For example, the U phase of the second coil 13B may include a plurality of sub-coils S1-S6, which may be wound around the stator 11, so that the second coil 14 may include a plurality of sub-coil groups SG1-SG2, and The number of sub-coils of each sub-coil group is 3 (odd number), and the sub-coil groups SG1-SG2 may be connected in parallel, and the number of pole pairs of the second coil 14 may be an integral multiple of the number of sub-coils of each sub-coil group SG1-SG2.
如圖所示,第二線圈13B包含6個子線圈S1-S6組成二個子線圈組 SG1-SG2,子線圈S1、子線圈S3及子線圈S5串聯形成一個子線圈組SG1,子線圈S2、子線圈S4及子線圈S6串聯形成一個子線圈組SG2,子線圈組SG1與子線圈組SG2並聯,圖中箭頭AR2所示之定子11圓周方向為機械角0-360度。 As shown, the second coil 13B includes six sub-coils S1-S6 to form two sub-coil groups. SG1-SG2, sub-coil S1, sub-coil S3 and sub-coil S5 are connected in series to form one sub-coil group SG1, sub-coil S2, sub-coil S4 and sub-coil S6 are connected in series to form one sub-coil group SG2, sub-coil group SG1 and sub-coil group The SG2 is connected in parallel, and the circumferential direction of the stator 11 indicated by the arrow AR2 in the figure is a mechanical angle of 0-360 degrees.
由上述可知,較佳的,當各個子線圈組SG1、SG2之子線圈之數量為奇數,且沿定子11之圓周之機械角之0~360度上或第一線圈13A之磁場之電氣角之0~360度上平均分佈時,各個子線圈組SG1、SG2之該些子線圈可為串聯,而該些子線圈組SG1、SG2之間可為並聯。當然,在另一較佳的實施例中,該些子線圈組SG1、SG2之間可為串聯。 It can be seen from the above that, when the number of sub-coils of each sub-coil group SG1, SG2 is an odd number, and the electrical angle of the magnetic field of the first coil 13A is 0 to 360 degrees along the circumference of the stator 11 or 0. When the average distribution is ~360 degrees, the sub-coils of the respective sub-coil groups SG1, SG2 may be connected in series, and the sub-coil groups SG1, SG2 may be connected in parallel. Of course, in another preferred embodiment, the sub-coil sets SG1, SG2 may be connected in series.
當然,其它較佳的實施例中,各個子線圈組SG1、SG2之該些子線圈可為並聯,子線圈組SG1與子線圈組SG2則可以是以串聯或並聯的方式連結。 Of course, in other preferred embodiments, the sub-coils of the sub-coil groups SG1 and SG2 may be connected in parallel, and the sub-coil group SG1 and the sub-coil group SG2 may be connected in series or in parallel.
綜合上述,為了維持馬達驅動時良好的獨立性,以分別獨立地驅動第一轉子12A及第二轉子12B,進而達到精準的馬達控制,本發明之實施例提出了幾個子線圈的較佳的串並聯原則。當第一線圈13A極對數S1=1時,若第二線圈14有n個子線圈,其中n>1,至少有s種串聯方式,而s為n不等於一的因數的數量,該因數的集合為A={n1,n2,...,ns}。例如n=4時,n1=4,n2=2,s=2。如ni=k時,該k個子線圈的位置需平均分佈於定子11的圓周上,即機械角之0~360度上或第一線圈13A之磁場之電氣角之0至360度,且該k個子線圈可彼此串聯或並聯,而串聯的子線圈之間則可為並聯或串聯。 In summary, in order to maintain good independence during motor driving to independently drive the first rotor 12A and the second rotor 12B to achieve precise motor control, embodiments of the present invention propose a preferred string of several sub-coils.

When the first coil 13A has a pole pair number S1=1, if the second coil 14 has n sub-coils, where n>1, there are at least s in series, and s is a number of factors in which n is not equal to one, the set of factors Is A={n 1 , n 2 ,...,n s }. For example, when n=4, n 1 =4, n 2 =2, and s=2. If n i =k, the positions of the k sub-coils need to be evenly distributed on the circumference of the stator 11, that is, 0 to 360 degrees of the mechanical angle or 0 to 360 degrees of the electrical angle of the magnetic field of the first coil 13A, and The k sub-coils may be connected in series or in parallel with each other, and the sub-coils connected in series may be connected in parallel or in series.
第一線圈極對數S1>1時,若第二線圈有nq個子線圈,其中n>1,至少有s種串聯方式,而s為n不等於一的因數的數量,該因數的集合為A={n1,n2,...,ns}。例如n1=4時,n2=2,s=2。如ni=k時,該k個子線圈的位置需 平均分佈於定子11上第一線圈13A產生之磁場的電氣角圓周上,即電氣角由0至360度,且該k個子線圈可彼此串聯或並聯,而串聯的子線圈之間則可為並聯或串聯。 When the first coil pole pair S1>1, if the second coil has nq sub-coils, where n>1, there are at least s series connection manner, and s is the number of factors that n is not equal to one, the set of factors is A= {n 1 , n 2 ,...,n s }. For example, when n 1 = 4, n 2 = 2 and s = 2. If n i = k, the positions of the k sub-coils need to be evenly distributed on the circumference of the electrical angle of the magnetic field generated by the first coil 13A on the stator 11, that is, the electrical angle is from 0 to 360 degrees, and the k sub-coils can be connected in series with each other. Or in parallel, and the sub-coils in series can be connected in parallel or in series.
透過上述的設置,可使本發明之混合式雙轉子馬達結構1之第一線圈13A及第二線圈13B之間的磁通鏈結降低,如此則可以維持馬達驅動時良好的獨立性,使操控時能夠同時對第一轉子12A及第二轉子12B進行獨立控制,進而達到精準的馬達控制,以提供更佳的效能。 Through the above arrangement, the flux linkage between the first coil 13A and the second coil 13B of the hybrid dual-rotor motor structure 1 of the present invention can be reduced, so that the motor can be maintained with good independence during driving, and the control can be performed. The first rotor 12A and the second rotor 12B can be independently controlled at the same time to achieve precise motor control to provide better performance.
又,透過上述的設置,混合式雙轉子馬達結構1之定子11可具有多種不同的線圈配置,使混合式雙轉子馬達結構1可以具備不同的動力特性,因此應用更為廣泛,使用上更具彈性。 Moreover, through the above arrangement, the stator 11 of the hybrid dual-rotor motor structure 1 can have a plurality of different coil configurations, so that the hybrid dual-rotor motor structure 1 can have different dynamic characteristics, so that the application is more extensive and the use is more elasticity.
此外,由於第一線圈13A及第二線圈13B之間的磁通鏈結已有效地降低,定子11也不需要設置不導磁層,使混合式雙轉子馬達結構1之體積、重量及成本大幅降低。 In addition, since the flux linkage between the first coil 13A and the second coil 13B has been effectively reduced, the stator 11 does not need to be provided with a non-magnetic conductive layer, so that the volume, weight and cost of the hybrid dual-rotor motor structure 1 are large. reduce.

The second coil 13B can be wound around the stator teeth 111. The second coil 13B may include a plurality of sub-coil groups, which may be connected in series or in parallel. Each sub-coil group includes a plurality of sub-coils, which may be connected in series or in parallel, and the second coil 13B The logarithm may be an integer multiple of one of the pole pairs of the first coil 13A.

同樣的,第一線圈13A可包含變極結構,變極結構可包含複數個切換元件,並可藉由切換該些切換元件以改變第一線圈13A之極數;第二線圈13B也可包含變極結構,變極結構可包含複數個切換元件,並可藉由切換該些切換元件以改變第二線圈13B之極數。因此,混合式雙轉子馬達結構1可藉由整合此特殊的變極結構以提供更多不同的動力特性如同上述,為了維持馬達驅動時良好的獨立性,進而達到精準的馬達控制,使操控時能夠同時對第一轉子12A及第二轉子12B進行獨立控制,本實施例也可應用特殊的線圈配置。然而,本實施例之線圈配置可以與前述實施例類似,故不在此多加贅述。 Similarly, the first coil 13A may include a pole-changing structure, the pole-changing structure may include a plurality of switching elements, and the number of poles of the first coil 13A may be changed by switching the switching elements; the second coil 13B may also include The pole structure, the pole-changing structure may include a plurality of switching elements, and the number of poles of the second coil 13B may be changed by switching the switching elements.

The first rotor 12A and the second rotor 12B can be independently controlled at the same time, and a special coil configuration can also be applied in this embodiment. However, the coil configuration of this embodiment can be similar to the foregoing embodiment, and therefore will not be further described herein.
值得一提的是,習知技藝之雙轉子馬達結構之定子需要設置不導磁層,以降低多個線圈之間的干擾,因此大幅地提高了其體積、重量及成本。相反的,在本發明之一實施例中,混合式雙轉子馬達結構可具備雙轉子及 單定子,且定子中不需要設置不導磁層,因此混合式雙轉子馬達結構之體積、重量及成本可以進一步降低。 It is worth mentioning that the stator of the conventional dual-rotor motor structure needs to be provided with a non-magnetic conductive layer to reduce the interference between the plurality of coils, thereby greatly increasing its volume, weight and cost. In contrast, in one embodiment of the present invention, the hybrid dual-rotor motor structure can be equipped with a dual rotor and The single stator and the non-magnetic conductive layer are not required in the stator, so the volume, weight and cost of the hybrid dual-rotor motor structure can be further reduced.
又,本發明之一實施例中,混合式雙轉子馬達結構可利用特殊的線圈配置來使多組線圈間的磁通鏈結降到最低,使多組線圈可以更容易獨立地被驅動,故可以使馬達的效能達到最佳化。 Moreover, in one embodiment of the present invention, the hybrid dual-rotor motor structure can utilize a special coil configuration to minimize the flux linkage between the plurality of sets of coils, so that the plurality of sets of coils can be driven more easily and independently. The performance of the motor can be optimized.
本發明之一實施例中,習知技藝之雙轉子馬達結構由於設計上的缺失,故其定子無法具有多種不同的線圈配置,因此無法提供多種不同的動力特性。相反的,本發明之一實施例中,混合式雙轉子馬達結構可利用之定子可具有多種不同的線圈配置,使混合式雙轉子馬達結構可以具備不同的動力特性,因此應用更為廣泛,使用上更具彈性。 In one embodiment of the present invention, the dual rotor motor structure of the prior art cannot have a variety of different coil configurations due to the lack of design, and thus cannot provide a variety of different dynamic characteristics. In contrast, in one embodiment of the present invention, the hybrid dual-rotor motor structure can utilize a variety of different coil configurations for the stator, so that the hybrid dual-rotor motor structure can have different dynamic characteristics, so the application is more widely used. More flexible.
此外,習知技藝之雙轉子馬達結構由於設計上的缺失,故無法滿足低速高扭力及並能同時兼顧寬廣轉速域的需求。相反的,本發明之一實施例中,混合式雙轉子馬達結構可在定子上同時設置二組線圈,且二組線圈之間不會相互干擾,故可視情況地針對二組線圈分別進行激磁以驅動雙轉子,以分別提供高扭力及高功率等不同的特性,故能達到低速高扭力及並能同時兼顧寬廣轉速域的需求。 In addition, due to the lack of design, the dual-rotor motor structure of the prior art cannot meet the requirements of low speed and high torque and can simultaneously satisfy a wide range of speeds. In contrast, in an embodiment of the present invention, the hybrid dual-rotor motor structure can simultaneously set two sets of coils on the stator, and the two sets of coils do not interfere with each other, so the two sets of coils can be separately excited by the case. The two rotors are driven to provide different characteristics such as high torque and high power, so that low speed and high torque can be achieved and the wide rotation speed range can be simultaneously considered.
再者,本發明之一實施例中,混合式雙轉子馬達結構可以在不提高整體功率的前提下達到低速高扭力,因此即使應用上有空間及重量的限制,本發明之混合式雙轉子馬達仍然可以發揮極佳的效能,故很適合應用於電動車之輪內驅動馬達或一體式啟動發電機等等具有空間及重量限制的應用。 Furthermore, in one embodiment of the present invention, the hybrid dual-rotor motor structure can achieve low speed and high torque without increasing the overall power, so the hybrid dual-rotor motor of the present invention can be used even if there is space and weight limitation in the application. It still has excellent performance, so it is suitable for applications with space and weight limitations such as in-wheel drive motors for electric vehicles or integrated starter generators.
請參閱第8圖,其係為本發明之混合式雙轉子馬達結構之第四實施例之示意圖。如圖所示,混合式雙轉子馬達結構1可包含定子11、第一轉子12A、第二轉子12B、第一線圈13A、第二線圈13B、減速機15、換流器 16、及開關17A、17B。 Please refer to FIG. 8, which is a schematic view of a fourth embodiment of the hybrid dual rotor motor structure of the present invention. As shown, the hybrid dual rotor motor structure 1 can include a stator 11, a first rotor 12A, a second rotor 12B, a first coil 13A, a second coil 13B, a reducer 15, and an inverter. 16, and switches 17A, 17B.
第一線圈13A及第二線圈13B可繞設於定子11上。換流器16可透過開關17A連結於第一線圈13A,並可透過開關17B連結於第二線圈13B以分別驅動第一轉子12A及第二轉子12B,而第一轉子12A可連結於輪軸18,第二轉子12B可連結於減速機15之輸入端,而減速機15之輸出端則可連結於輪軸18。 The first coil 13A and the second coil 13B may be wound around the stator 11. The inverter 16 is coupled to the first coil 13A via the switch 17A, and is coupled to the second coil 13B via the switch 17B to drive the first rotor 12A and the second rotor 12B, respectively, and the first rotor 12A can be coupled to the axle 18, The second rotor 12B can be coupled to the input end of the reducer 15, and the output end of the reducer 15 can be coupled to the axle 18.
同樣的,在本實施例中,輪軸18的轉速為W,第二轉子12B的磁鐵組的極對數為第一轉子12A的磁鐵組的極對數的4倍,因此第二轉子12B的電氣角變化的速度也會是第一轉子12A的電氣角變化的速度的四倍。因此,在本實施例中,為了使第一轉子12A、第二轉子12B在同一個換流器16的驅動下能夠達到使第一轉子12A之三相線圈之反電動勢與第二轉子12B之三相線圈之反電動勢同相的目的,本實施例之減速機15之減速比可以設計為1:4,也就是說,減速機15之減速比之比值可等於第一轉子12A的磁鐵組的極對數與第二轉子12B的磁鐵組的極對數的比值,如此則可以達到上述的目的。 Similarly, in the present embodiment, the rotational speed of the axle 18 is W, and the number of pole pairs of the magnet group of the second rotor 12B is four times the number of pole pairs of the magnet group of the first rotor 12A, so the electrical angle of the second rotor 12B changes. The speed will also be four times the speed at which the electrical angle of the first rotor 12A changes. Therefore, in the present embodiment, in order to enable the first rotor 12A and the second rotor 12B to be driven by the same inverter 16, the back electromotive force of the three-phase coil of the first rotor 12A and the third rotor 12B can be achieved. For the purpose of the counter electromotive force of the phase coil being in phase, the reduction ratio of the reducer 15 of the present embodiment can be designed to be 1:4, that is, the ratio of the reduction ratio of the reducer 15 can be equal to the number of pole pairs of the magnet group of the first rotor 12A. The ratio of the number of pole pairs of the magnet group of the second rotor 12B can achieve the above object.
而在輪軸18之轉速W提高到一定程度時,第一轉子12A及第二轉子12B可能會發生不同步的現象,此時則可透過開關17A、17B選擇性地斷開換流器16與第一線圈13A及第二線圈13B中之一的連結,藉此使混合式雙轉子馬達結構1能穩定的作動。 When the rotational speed W of the axle 18 is increased to a certain extent, the first rotor 12A and the second rotor 12B may be out of synchronization. At this time, the inverter 16 and the second can be selectively disconnected through the switches 17A and 17B. The connection of one of the coil 13A and the second coil 13B allows the hybrid dual-rotor motor structure 1 to be stably operated.
藉由上述的設計,混合式雙轉子馬達結構1可以僅透過一個換流器16即可使第一轉子12A及第二轉子12B同步,因此可以使第一轉子12A、第二轉子12B之體積、重量及成本大幅地降低。除此之外,上述的設計更可以混合式雙轉子馬達結構1具有更多不同的動力特性,使其應用上更為廣泛。 With the above design, the hybrid dual-rotor motor structure 1 can synchronize the first rotor 12A and the second rotor 12B by only one inverter 16, so that the volume of the first rotor 12A and the second rotor 12B can be made. The weight and cost are greatly reduced. In addition, the above design makes the hybrid dual-rotor motor structure 1 have more different dynamic characteristics, making it more widely used.
值得一提的是,習知技藝之雙轉子馬達結構需要透過二個換流器來分別驅動二個轉子,因此其成本較高,相反的,本發明之一實施例中,混合式雙轉子馬達結構可包含減速機等結構,因此雙轉子可僅透過一組換流器來驅動,故可以進一步降低混合式雙轉子馬達結構之體積、重量及成本,且能提供更多不同的動力特性。 It is worth mentioning that the dual-rotor motor structure of the prior art requires two rotors to drive the two rotors respectively, so that the cost is high. Conversely, in one embodiment of the invention, the hybrid dual-rotor motor The structure can include a structure such as a reducer, so that the dual rotor can be driven only by a set of inverters, so that the size, weight and cost of the hybrid dual-rotor motor structure can be further reduced, and more different dynamic characteristics can be provided.
